Critical imperfections such as Debond, voids and cracks decrease performance of composite structure. Accurate evaluation of properties of composites with above imperfections prevents the catastrophic failure of designing components. In this study, finite element analysis is performed to determine the effective elastic properties of debonded unidirectional composites with Micro and Macro-mechanics approaches. Intensity of fully debonded fibers on the behavior of total composite material is studied. The applicability of the present work is explored for conventional fiber of boron with homogenized nano fullerene particle mixed polymer matrix. The effect of debonding of boron fiber reinforcement on the effective Young’s modulus and Poisson’s ratio of the composite is demonstrated. The study revealed that transverse Young’s modulus (E2) is extensively affected than longitudinal Young’s modulus due to debond.
